Question 1 Light of wavelength 542 nm passes through two slits that are separated by 4.9 µm. At what anglular deviation, as measured from the middle of the central maximum, would the 1st order bright fringes appear on a screen that is 2.6 meters away?

9.6 degrees3.2 degrees16.1 degrees6.4 degrees

Question 2 What is the linear separation on the screen between adjacent bright fringes?

2.89 x 10-1 meters

Question 3 In a totally darkened room, what would be the maximum possible number of bright fringes, including the central maximum, that could be viewed on the screen?

19 fringes9 fringes18 fringes10 fringes

Question 4 Point P has a linear deviation of 0.91 meters above the middle of the central maximum. Is point P located in a bright or dark fringe?

cannot be determinedbrightdark

Question 5 If light of the same wavelength were to pass through two slits that were separated further apart, how would the distance between the bright fringes on the screen change?

the distance would increasethe distance would decreasethe distance would remain the same

Question 6 If light of a longer wavelength were to pass through the original two slits, how would the distance between the bright fringes on the screen change?

the distrance would remain the samethe distance would increasethe distance would decrease
